Methods and steps for selecting standard molds

There are two ways to choose the standard mold: one is the standard usage, that is, the structure of the standard is completely adopted, and the size range of the components is selected; The second is the modified usage, that is, the structural form stipulated in the standard can be changed by proper secondary processing of the standard parts; Some standard parts can not be used, so as to expand the application range of standard molds. The following mold manufacturers detailed for you to introduce the selection of standard mold methods and steps, details are as follows...

Choice of mold type: according to the mold cavity, core structure form, demoulding action, casting form to determine the mold structure model

The selection of mold series: according to the larger overall size of the parts, the structural action range of the mold parts of the parts (side parting, side core-pulling, etc.), the layout of the additional action parts, the cooling system, etc., select the template surface size of the mold (the size should meet the installation requirements of the selected injection machine for the mold) to determine the series of mold;

Selection of mold mold specifications: analyze the stressed parts of the template, calculate the strength (stiffness), and determine the thickness of each template and the length of the guide post within the specified thickness range of the template to determine the specification of the mold;

Other precautions for mold selection: After the mold surface size is determined, the aperture size of the guide post, guide sleeve, push bar, fastening screw hole, the size of the matched push plate and the pad can be found from the standard; Considering the pushing distance of the parts and adjusting the thickness of the die, the thickness of the pad and the length of the push rod are determined. Verify whether the total thickness of the mold meets the requirements of the selected injection machine, and if it does not meet the requirements, appropriate additions or subtraction are made to some modules or pads to make them meet the requirements;
